Medium carbon steel: carbon content (C: 0.25% < C ≤ 0.6%) can also contain a small amount of manganese (0.70% ~ 1.20%) in addition to carbon. It's thermal processing and cutting performance are good, but its welding performance is poor. The strength and hardness are higher than low-carbon steel, but the plasticity and toughness are lower than low-carbon steel. Therefore, medium-carbon steel is the most widely used in various uses of medium-strength levels. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts. Medium carbon steel is mainly used to manufacture high-strength moving parts, such as air compressors, pistons of pumps, impellers of steam turbines, shafts, worms, gears of heavy machinery, etc., parts with wear-resistant surfaces, crankshafts, machine tools Spindle, rollers, fitter tools, etc.
CNC machine parts processing and manufacturing has the following advantages;
1. The number of tooling is greatly reduced, and complex tooling is not required to process parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for developing and modifying new products.
2. The processing quality is stable, the processing accuracy is high, and the repetition accuracy is high, which is suitable for the processing requirements of aircraft.
3. In the case of multi-variety and small-batch production, the production efficiency is higher. CNC machining can reduce the time for production preparation, machine tool adjustment, and process inspection, and reduce cutting time due to using the best cutting amount.
4. It can process complex profiles that are difficult to process by conventional methods, and even some difficult-to-observe processing parts.
The disadvantage of CNC machining is that the machine tool equipment is expensive and requires a high level of maintenance personnel.
CNC machining is decoded by a computer, causing the machine tool to move and machine the part. The blank is processed into a semi-finished product by a cutting tool.
